Re: About ceph disk slowops effect to cluster

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi Yang and Anthony,

I found the solution for this problem on a HDD disk 7200rpm

When the cluster recovers, one or multiple disk failures because slowop
appears and then affects the cluster, we can change these configurations
and may reduce IOPS when recovery.
osd_mclock_profile=custom
osd_mclock_scheduler_background_recovery_lim=0.2
osd_mclock_scheduler_background_recovery_res=0.2
osd_mclock_scheduler_client_wgt
